Surface Metrology

REO maintains 14 Fizeau interferometers for accurate measurement of surface figure, utilizing several different configurations for both in-process and final product measurement of surface figure of flat and spherical surfaces. REO has interferometers at 633nm and 1064nm. These instruments normally have an absolute accuracy of approximately l/100. REO maintains interferometers with apertures of up to 150mm diameter, with lateral resolution of up to 100um.

Thin Film Coating

Over 20 years ago, REO became the first company to commercially provide Ion Beam Sputtered (IBS) thin film coatings. Today, we have expanded our technology to produce the highest quality thin films performing a range of functions across the full optical spectrum from the deep UV (190nm) through the long wave IR (14um). With a total of 35 coating chambers in operation, REO’s ability to produce the highest performance, lowest loss, most durable thin films across the spectrum is unmatched in the world.

Laser Damage Testing

REO provides some of the highest laser damage resistant optics in the world and is committed to the highest possible standard for testing and qualification of these optics. With our own fully automated laser damage test capability, REO not only conducts routing production testing of our products, but also continuously advances the state of the art in understanding laser damage mechanisms and test methodologies.

REO’s primary test system is comprised of a ~20ns pulse length 1064nm laser induced damage threshold (LIDT) test system according to ISO 21254-2 or other similar test protocols.

Facilities

Our factory has been built and organized for optics, thin film coatings and assembly fabrication. Clean rooms, state of the art metrology and our laminar flow production areas for contamination controls are just the foundation of what we do to ensure excellence.
